If you notice yourself doing any of these things, take a moment to reflect on why you are feeling so uneasy around people. Or for those who have noticed a friend acting this way, understand that their behavior isn't a reflection of you. Your friend doesn't hate you, they're just taking some time to recoil and recharge their energy. When those people who are a little more introverted or socially anxious get into these funks, they don't stop loving their friends. I will tell you from my own experience, I'm so thankful for the good friends I have who understand why I want a little space sometimes and support me through my funks.
